APPARATUS FOR SATURATING WOOD.

SPECIFICATION forming part of Letters Patent No. 666,915, dated January29, 1901. Application ned Jury 5, 1900. serai No. 22,517. (No model.)

.To all whom it may concern,.-

Beit known that I, MAX BACHERT, a citizen of the United States, residingin the borough of Manhattan, city, county, and State of New York, haveinvented certain new and useful Improvements in Apparatus for SaturatingWood, of which the following is a specification.

My invention relates to an improvement in apparatus for saturating wood,and is particularly directed to improve the apparatus shown in UnitedStates Letters Patent No. 602,713, dated April 19, 1898, to Max Bachertand David W. ONeil, although the invention is not limited to suchapparatus.

The invention has for its principal object to produce a construction inwhich wood may be eihciently saturated, let us say, with a fireprooiingsolution and at the same time clamped firmly in place, so that the carsor other wood-carriers may be run in and out of the saturating-tankfreely, as the wood being retained in place will not be liable to catchor strike against the sides of the tank, so as to bind.

In the accompanying draWingsI have shown a structure in which myinvention is embodied.

In the drawings, Figure 1 is a vertical section across a Bachert andONeil saturatingtank, showing my improvements applied thereto. Fig. 2 isa broken-away side elevation of a portion of the tank or cylinder, whichcylinder is in many cases of considerable length-say ninety feet. Fig. 2also shows the section-line l 1, on which Fig. 1 is taken. Fig. 3 is asection on the line 3 of the curved clamps.

In the drawings, a is the saturation-tank, preferably in the form of ahorizontal cylinder suitably supported and of considerable length. Thiscylinder is provided Within with rails l), upon which runs a suitableWood carrier or car c, of which there may be several to accommodate along pile of lumber. Located within the tank are suitable clamps d,which are preferably curved and T-shaped in cross section, as shown inFig. 3. These clamps are preferably suspended by their upper ends fromthe upper part of the woodsaturation tank by links e, which are hereinshown as pivotally connected to the clamps and to ears depending fromthe inner face of the tank. These clamps are adapted to partiallysurround or encircle the body of wood on the car or other wood-carrierand are provided with suitable actuating means, shown in the presentinstance as ascrew plunger f, fitting loosely in a socket g, secured tothe clamp and maintaininga freely-swinging connection between the clampsd and the actuating-plungers f. The plungers pass through a suitablegland and stuffing-box arrangement 71J and are shown as provided withhandwheels 't'. Sets of these clamps and their actuating means areplaced at intervals along the tank and serve when brought into action tovery efficiently clamp the wood upon the wood-carrier, so that the saidwood will not become displacedor folded up by the fireprooin g fluidwhen it enters,nor will the wood be clamped so firmly as to prevent theentry of the fluid into its porous spaces.

I am quite well aware that it has been heretofore proposed to thrustdown a plunger upon the top of the pile of wood upon the car; but thestructure which I describe herein is much superior and operatesin thebest possible manner.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The combination of a wood-saturating tank, a wood-carrier adapted tofreely move in the Y said tank, and pivotally mounted clamps havingoperating means therefor eX- tending outside of the Wood-saturationtank.

2. The combination of a closed Wood-saturation tank, a wood-carrieradapted to move freely in said tank, clamps adapted to partiallysurround the said wood and to embrace the same from opposite sides, andoperating means extending outside of the wood-saturation tank foractuating the said clamps.

3. The combination of a wood-saturation tank, a car or wood-carrieradapted to move freely therein and a pluralityl of clamps pivotallysuspended in the said tank and of such shape as t-o partially surroundthe Wood-car and operating means for the clamps extending outside of thewoodfsaturation tank.
